The SS3 subset of the Montreal Archive of Sleep Studies (MASS) cohort is an open-access database of laboratory-based polysomnography (PSG) recordings defined as :
- 62 subjects (age 42.5±18.9 years, age range: 20-69 years)
- 29 males (age 40.4±19.4 years, age range: 20-69 years)
- 33 females (age 44.2±18.6 years, age range: 20-69 years)
- 62 PSG recordings (whole night) "* PSG.edf"
- 20 electrodes in the EEG montage
- reference is linked-ear reference with a 10 kΩ resistance (LER)
- 2 EOG channels
- 3 referential EMG
- 1 ECG channel
- 62 Sleep staging files "* Base.edf"
- Sleep stage scoring rules : AASM
- Page size (s) : 30
Notes: The EMG channels are referential and not bipolar as stated in the paper (O'Reilly 2014).
Sleep stage scoring does not necessarily start at the beginning of the PSG recording.
Sleep Annotations are available in the dataset named "SS3 Sleep Annotations" (https://doi.org/10.5683/SP3/YD8AYI).
